Radxa CM5 on RPi CM4 IO Board - HDMI not detected

I tried both of these images:

I’m able to login via ssh and the bookworm image I can get the USB ports but still no HDMI

Tried the other port with the same result.

I looked at rsetup and there is nothing there for hdmi drivers.

I also tried looking and rsetup and didn’t see any overlays for the HDMI.

Pls reload the image,and only hdmi0 is support output.

I tried both.

Here is the guide I followed:


Is there an updated one for Radxa CM5?
